Ok this is interesting. Do you have a source for this figure? You are saying that 1.3 million EVs would be enough to support the UK were it to transition to wind + solar entirely (my initial question)?

Probably a good move by Tesla. I’ve been on team EV for a decade and hope V2G works out. But I’ve yet to see a convincing argument that it will work as the main storage method.

In regards to V2G. Tesla is not even supporting bi-directional charging at this point and it is just now starting to become a bit more common in newer models. It would be interesting to see more detailed example about this. You would also need to include the usage of industry and commercial which as far as I know together account for more than residential usage. How about availability in terms of SOC and being plugged in or not. I think this is a bit more difficult to solve than you are alluding to but I’m happy to be proved wrong.

Interesting product. Reading about it quickly it seems to have a problem with self discharge. But perhaps they have ironed out that problem. There is no shortage of promising battery news, but there seems to be a problem getting them to mass production. Hoping this one is different.

To those of you who propose 100% renewables + storage. In cases with no access to hydro power. How much energy storage do you need? How does it scale with production/consumption? What about a system with 100TWh yearly production/consumption?

Not sure how app.electricitymaps.com gets their data but according them SA uses around 30% gas. How much are you saying they are using?
